LUBRICATING MEANS.

Original application filed October 11, 1920, Serial No. 416,148. Dividedand this application filed January 28 1925.

My invention relates to the art of forced I mg 1n cylinder 16.

lubrication of machine parts, such as the rotary bearings of motorvehicles and other equipment, in which a pressure tight receivingfitting is provided'in connection with each hearing or part tobelubricated, to receive and retain lubricant forced into the same. Suchsystems and the fit-tings therefor are 'old and well knownsin the artand per se form no part of the present invention, which relates'jto themeans employed for forcing the lubricant into the fitting.

Among the primary objects and advantages of the invention may beenumerated.

First. The improvement of the mechanical means for commercializingdistribution of lubricant for use in lubricating guns.

Second. Eliminating the possibility of contamination of lubricant withdirt or grit in transfer from'the manufacturer to the bearings,especially in that portion of the transfer between the retail dealer andthe lubricant gun.

n Third. Increasing the liability of a supply ofv the proper lubricantto each bearing by providing for changing from one lubricant to anotherwith a maximum of convenience, aminimum-of waste, and a minimum ofintermixture of the different lubricant-s.

Fourth. Reduction of the sum total of the equipment required for forcedlubrication to a minimum of bulk and cost.

Further objects and advantages of the invention will be apparentas thedescription proceeds. V

In the accompanying drawings:

Fig.- 1 is a plan-view of one type paratus according; to the invention;

" Fig. 2 is a sideeleration; and

Fig. 3 is an'end elevation of the same parts.

The pivoted-levers 10 and 12 are adapted to move the parallel jaws 14and 15 toward and away from each other, the parts being ordinarily heldin the expanded position shown in Fig. 2 by a tension's'pring 18. Thislinkage is well known in various uses in other arts.

Jaw 14 carriescylinder 16 integral therewith or permanently attachedthereto. Cylinder 16 has the terminal connection 17 built close up tothe end of the cylinder. The

Serial No. 5,269. other parallel jaw 15 carries piston 2O'slid- Inletport 22 will be sealedby piston 20 shortly after the beginning of thestroke after which the contents of cylinder 16 will beforced out intoterminal 17 and into any sultable fitting to which the same may becoupled.

It will be observed that when the piston I is at the end of its strokethe shortconnecting passage 24 through partition 26 repre sents theentire volumeoflubricant that will remain in the device in case it isdetachedfrom the fitting withouti'withdrawing the piston.

The

.be suffic'iently spaced from the hand of the operator employed tooperate levers 10 and 12.

It will be noted that when a change is to be made from one kind oflubricant to an-. other, piston 20 can be left atthe inner'end of itsstroke, while the device is removed from the fitting, and thereafterreservoir 28 may be unscrewed from the threaded connection at 32 to bereplaced by a duplicate container filled with the other kind of lubri-"cant. Such a replacement wil deliver to" lub ricant reservoir. 28 is inthe "form: of a flexible and collapsible metallic tube or thebearingintended to receive the new lu bricant a quantity of the oldlubricant represented only by the relative negligible capacity ofpassageway 24 and port 22'.

This application is a division of my pending application,

' Without further elaboration, the forego- Serial No. 416,148, filed ingwill so fully explain the gist of my invention, that others may, byapplying cur-- rent'knowledge, readily adapt the same for use undervarious conditions of service,

Without eliminating certain features which may properly be said toconstitute the essential items of novelty involved, which items areintended to bedefined and secured to me by the following claims.

I claim:

1. A forced lubrication equipment, c0mprising articulated levers to beheld in one hand and collapsed thereby, lubricant injecting meansactuated by said levers, and a collapsible tube lubricant containerdetachably connected to said injecting means and extending back at rightangles to the general direction of said levers.

2. A forced lubrication equipment, comprising articulated levers to beheld in one hand and collapsed thereby, lubricant injecting meansactuated by said levers, and a collapsible tube lubricant containerdetachably connected to said injecting'means, said container extendinglaterally with respect to said levers, and said injecting means having acoupling terminal opening laterally in the opposite direction.

In Witness whereof, I hereunto subscribe 25 my name this 15 day ofJanuary, 1925'.

JOHN L. OREVELING.
